It has been rumoured that the PS4 and next Xbox will be releasing next year around the holiday season. According to GameStop boss Paul Raines, that will not be the case. Raines has explained “The Wii U, we expect it at holiday. This week, I’m getting a lot of rumors that are very interesting about 2013. We have not been expecting two more consoles in 2013. We’re expecting Wii U this holiday, another one next year, and another one in ’14.”
Sony has stated in the past they aren’t racing to get their system out before Microsofts, so there could be some truth to this. At the beginning of this generation of consoles Xbox360 launched one year ahead of the Wii and PS3.
